Raz B says he’s going to tough it out on the B2K reunion tour, despite fearing for his own safety … and feeling less than appreciated by his group mates.

We got Raz in Brooklyn Wednesday afternoon — ahead of B2K’s show Thursday in Rochester, NY — and the singer tells us he’s no longer throwing in the towel, despite shocking fans by announcing he was quitting … just a few days into the highly anticipated tour.

Something or someone changed his mind — Raz says he’s gonna continue touring with Omarion, Lil Fizz and J Boog … but he still has a few demands, like beefing up his personal security.

As you know … Raz ranted Tuesday night on IG, telling fans he was quitting and laying blame on the group’s former manager, Chris Stokes, who Raz has accused of sexual abuse.

Translation: Chris is the reason Raz doesn’t feel safe on tour.

The good news for B2K fans … Raz says the group is getting along better now, and the tour is in full effect.
